Effects Of Ph

Konjac Glucomannan (KGM) was modified by maleic anhydride (MA). The influences of processing parameters on the mechanical properties of KGM films were investigated through orthogonal experiments. The results showed that the effects of pH, temperature and time of KGM swelling on tensile strength and folding endurance of modified KGM membranes were insignificant (F<F0.05). The quantity of MA affected slightly on the tensile strength (F<F0.05), but its effect on the folding endurance was significant (F>F0.01). Folding endurance and tensile strength of KGM membranes could be improved by proper addition of MA. The optimum conditions of KGM modification were that the mixture of KGM and MA was swelling at pH 4.0 and 60°C for 2 h, and then cast on a flat and dried at 50°C to give modified KGM membranes.

Konjac glucomannan (KGM) were modified by deacetylation with sodium hydroxide, calcium hydroxide, sodium carbonate, sodium phosphate, respectively and mechanical properties of modified KGM films were investigated. The modification mechanism was explored by FTIR. Results show that deacetylation of KGM play an important role on the flexibility of the modified membranes, and the flexibilities vary with different modifiers. The flexibility of the films modified by sodium hydroxide is significantly higher than that of the others. The modified films with good flexibility were prepared by simple steps as follows: NaOH modifiers and KGM (1%) were added to water, stirred until the pH arrived at 9. And then the KGM swelled at the temperature of 50°C for 2 hours, the modified KGM sol was cast onto glass plates, the modified membranes were formed after dried at 50°C.

Jackfruit (JS)-konjac glucomannan (KGM) blend films were prepared using different concentrations of JS, KGM and glycerol. Their mechanical properties were determined. All the films exhibited significantly higher values of tensile strength and elongation at break than those of neat JS films. The values varied considerably depending on KGM and glycerol content.Quercus infectoriaextract was embedded into the films and its release characteristics were controlled by changing the initial KGM content. This study suggests that the blend film has a potential use for advanced controlled release of bioactive extracts.
